ABOUT MODUSTEEL
Steel framing built
by builders,
not just sold to them.
ModuSteel is the manufacturing arm of a vertically integrated builder-developer. We design, roll-form, panelize, and ship cold-formed steel framing systems — and we also build with them. This is not a startup. It's a builder that decided to make its own steel.

THE STRUCTURE
The M4 Group
ModuSteel sits inside a vertically integrated operating group with active development projects, licensed general contractor partners, and active site-work operations across the Carolinas, Florida, and Alabama. Every panel we ship gets tested by our own crews first.
Our licensed general contractor partners self-perform sitework, public water, and utilities in addition to vertical construction. Foundation-to-frame coordination — the sequencing that makes panel delivery work — happens under one roof, not across three subcontract relationships.
This is not a venture-funded startup. M4 Development Holdings was founded by builders to solve the problems builders face — starting with the framing schedule.

IRONSIDE BY MODUSTEEL
PROGRAM IN DEVELOPMENTA nearshore vision.
A coordinated building system.
IRONSIDE is ModuSteel's proposed manufacturing program in Bonao, Dominican Republic. The plan brings light-gauge steel framing, standing-seam roofing, windows and doors, and project kitting into a coordinated production and delivery workflow.
For developers: villas, repeatable homes, ADUs and workforce housing.
For builders: framing packages, panelization and coordinated shell components.
For project teams: BIM coordination, quality checks and logistics planned around the job.
Manufacturing illustration. The Bonao facility is proposed; production capacity and free-zone status depend on development and approvals.

HOW WE OPERATE
Four principles that run the shop floor.
01
Vertical integration is the advantage
We don't sell steel to builders who figure it out themselves. We are the GC. We know what a framing crew needs on Monday morning — because we have one.
02
Shop-fabricated beats field-built
Panels assembled in a controlled shop environment are plumb, true, and sequenced. The jobsite is for erection, not fabrication.
03
Fixed price means fixed price
Material cost is locked at PO. Your budget recap won't have a line item for lumber surcharges mid-project. That's not a marketing claim — it's how the contract reads.
04
Builders don't need a pitch deck
We talk schedule, trade stack, and punch list. If you want to know what our panels do for your job cost, submit a plan set and we'll show you with numbers.
